I This inventionrelates to a float system for the supporting' wings offlying boats.

It is an object of the present invention to 'provide a float of the kindreferred to which can 6 be -made to disappear in the wing.

Avspecial object of the invention is to provide means for withdrawingthe oat in such a manner that it disappears entirely in the wing inspite of its relatively large dimensions with re-v 10 ,spect to thedepth of the wing.

With these and further objects in view, as may become apparent from thewithin disclosures, the invention consists not only in the structuresherein pointed out and illustrated by the drawing, but includes furtherstructures coming within the scope of what hereinafter may be claimed..v

. The character of the invention, however, may

be best understood by reference to certain of itsl 90 structural forms,as illustrated by the accompanying drawing in which Fig. 1 is adiagrammatical front elevation of one half of anying boat having theinvention applied thereto, while Fig. 2 is a plan view of the float inits operative 25 position. e,

` In the drawing.' a pair of supportingiioats I and 2 are provided whichcan be swung into the wing II as separate elements as indicated indotted lines but when swung out act practically 30 as a single floatunit as shown. 'I'he oat elements I and 2 are secured to arms 5 and 6which are pivoted in the wing II, on'shafts 1 and I and provided withtoothed segments 3 and i whichl mesh with each other. A pinion 9 on l5 ashaft III in the wing engages the toothed seg- Ament 3 for imparting theswinging motion to the iloats I and 2, through said segments 3 and 4 andsaid arms 5 and 6. To this end, the pinion l can be driven in eitherdirection, undercon- I0 trol of an operating member Il in the pilotsseat (not shown), for example, by means of an electric motor and/orsuitable. gearing' (not shown) `and through a transmission I5. The wingII is w formed with suitable recesses or cavities I2 and I3 for thereception of the floats. as indicated .in dotted lines. The boat hull isindicated at I6.

"It is also contemplated that a plurality of pairs of floats I, 2 may beprovided if required, for instance, for iiying' boats of a largerdisplacement.

It will thus be'understood thata 'iiying boat according to the presentinvention comprises a plurality of .oats which can be' received inseparate recesses of the supporting plane butv when swung out into theiroperative position act practically asa unitary float vforming a.favourable dynamic shape.

My novel arrangement of supporting floats provides for a r suicientcarrying capacity or buoyant power ofthe float and yet the floats can bewithdrawn into the interior of the wing in -such a manner that aconsiderable increase of the speed of the iiying boat or hydroplane isattained, due to the reduced aerodynamical resistance. l.

' I am aware fthat many further changes'mary be made andlnumerousedetails of construction may be varied through a wide rangewithout departing from the principles of this' invention, and I,-therefore, do not purpose limiting the patent granted hereon otherwisethan is necessitated by the prior art. v v I e I claim:

1.`A oat system for ying boats, comprising at least one pair ofswingable float elements and' means for swinging said oat elements intorecesses in the `wing of the aircraft and for swing-V ing out said oatelements to a position where they are close float.

2. Av iiying boat, comprising a boat hull, two wings, at least one pairlof swingable oat elements symmetrically arranged on the underside ofeach wing, means for swinging said float elements into separate recessesof said wings to form a substantially smooth face with the wings intheir inoperative condition and means -for swinging out -each pair kofoat elements to an operative position' in which said elements are closetogether and act as a unitary float.
